Kurzbeschreibung Morphologie | Morphometrie

Slender, elongate fish with elongate jaws forming a prominent pointed beak. Scales very small and numerous (Ref. 26938).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Occurs in weedy canals and tolerates poorly oxygenated waters and salinity to 40 ppt. Occurrence in saline (34-37 ppt.) water in Florida seems to be a case of local acclimatization. Formerly used in medical research. Total length 14 cm (Ref. 26938). Mostly freshwater, sometimes brackish (Ref. 26938). Piscivore (Ref. 79012).
